[PATCH] Fix block index check in insert_updated_phi_nodes_for

[Richard Biener]

This replaces a >= 0 block index check with the appropriate NUM_FIXED_BLOCKs,
the check is from times ENTRY_BLOCK was negative.

Re-bootstrap and regtest running on x86_64-unknown-linux-gnu.

        * tree-into-ssa.cc (insert_updated_phi_nodes_for): Fix block
        index check.
